Trouble Connecting Sony NSZ-GSZ7 and the Pace TDC777D DVR

I'm fairly new to the Google TV. I've connected my DVR to the HDMI in and I can receive the video fine. I'm trying to setup the device so I can get the channel up/down working. I attached the IR blaster to the Google TV and hung it over the IR receiver of the Cable Box. I typed in pace as the manufacturer but that specific model # does not show up when I type TDC. I then just hit the next button which gives 23 codes to try. Even holding the Remote Blaster in front of the IR on the DVR it can't find the codes. Any Ideas?
